Assignment of the operating and display unit -E87 -E87 as of Model Year 1997

Notes:

• ◆ Note the precise assignment when replacing an operating and display unit:

=> Parts List

• ◆ Different designs for the operating and display from chassis number 200000 of Model Year 1999 in vehicles with and without a radio navigation system (or radio with large display zone) with and without switches for heated seats (e.g. index "M", "N", "P" or "Q"

=> Parts List

• ◆ If the two display zones are not illuminated when the ignition is switched on, check the encoding of the -E87 and perform Electrical testing, Page 01-140

• ◆ If the two display zones are not illuminated on the operating and display unit -E87 with Part No. 8L0 820 043 from index "D" when the ignition is switched on, check the voltage supply from terminal 58d (dimmer) to the -E87 =>Electrical testing, Page 01-149.
• ◆ If the buttons on the operating and display unit -E87 with Part Number 8L0 820 043 from index "D" are not illuminated when the light is switched on, check the power supply 58s (locating light) to the -E87 =>Electrical testing, Page 01-149.

• ◆ When installing an operating and display unit -E87 with Part No. 8L0 820 043 from index "D" into a model year 1997 vehicle, or with Part No. 8L0 820 043 up to index "C" into a model year 1998 vehicle, it is not possible to adjust the brightness of the switch illumination.
• ◆ → Vehicles with a radio navigation system -A- are fitted with an operating and display unit -E87 with only one display. The selected functions are displayed in the buttons by the illumination of LEDs in the buttons.
  With this design of the -E87, the dash panel temperature sensor -G56, the temperature sensor blower -V42 and the heated rear window switch are integrated in the -E87.

• ◆ After renewing the -E87, always:
  - Check/correct code .
• ◆ If a new installed operating and display unit -E87 flashes after the ignition is switched on (for approx. 2 minutes), encode the -E 87 .
• ◆ The display on the -E87 may be switched from °C°F and vice versa by pressing the "temperature +" button with the "recirculated air" button pressed.
• ◆ If an -E87 operating and display unit with Part Number as of index "M" is replaced, the temperature is displayed on -E87 in °F in vehicles in which the allocation of the ignition key is transferred from the dash panel insert. The display can be switched from °F to°C on these vehicles by pressing the "temperature +" button and the "recirculated air button" button simultaneously. Each ignition key must be converted individually (as all ignition keys are not generally available in the workshop, the customer must be instructed as to how to perform the conversion).
